Employing the current limiting resistor is usually safe under the conditions that the circuit contains traditional 5mm LEDs, and the source voltage will not dramatically vary. Start by measuring the source voltage using a calibrated voltmeter. If the LED lighting design is automotive, remember to ...
刚下水时我还有一点儿害怕。不过,经过爸爸的指导,我学会了游泳。哈,今天玩得真开心。 Today, the daddy also led us to play.This time is swims.Just launched when I also had the little fear.The process daddy's instruction, I have learned the swimming.Kazak, plays today really happy.[translate]...
It includes a difficult circuit inside, but since it is enclosed in the integrated circuit. The two capacitors are located on the right side of the timer and these are required for the timer to work properly. The last part is the LED and the resistor. The resistor is used to restrict th...
This super-bright LED flasher circuit uses a single driver transistor, which takes its flash rate from a flashing LED. The flashlight cannot be changed by the brightness of the white LED. This LED can be adjusted by changing the resistor 1K across the 100u electrolytic to 10k. The 1K resis...
